How to use Tearing plugin?

[RickYang1]

Hi,
I added the TearingEngine component to the scn file, but when I imported the scn file in Unity, I encountered an error:

This is my scn file：
`

<VisualStyle displayFlags="showVisual showBehaviorModels" />

<DefaultAnimationLoop />
<DefaultPipeline verbose="0" />
<BruteForceBroadPhase/>
<BVHNarrowPhase/>
<CollisionResponse response="PenalityContactForceField" />

    <CGLinearSolver iterations="25" name="linear solver" tolerance="1.0e-9" threshold="1.0e-9" />
    <MeshGmshLoader name="meshLoader" filename="mesh/square3.msh" scale="10" createSubelements="true" />

        <OglModel name="Visual" color="red" />
        <IdentityMapping input="@.." output="@Visual" />
    </Node>
</Node>

Can I currently use the Tearing plugin in Unity? If not, what should I do to implement it?
Thank you in advance.

Hi,

the tearing will be part of the next release, here is the PR related to the integration: #94
If you want to test before, you need to add the Tearing plugin to the list of loaded plugin in Unity. This change in the PR

Best regards

Hi，
Thank you very much for your answer. Now I have resolved my error according to the method you provided, but when I run in Unity, the tearing did not occur：

20240626_191607.mp4

But it's possible in runsofa：

20240626_190842.mp4

Do I need to make any further modifications or obtain an available license.
Thanks in advance.

which version do you use? Are you compiling the plugin on your side?
you might need this fix: InfinyTech3D/Tearing@72be5ec

Thank you for your help. Currently, the testing is good. Looking forward to the next release.
